Abstract

The utility model relates to a laser distance measuring and positioning device used for mechanical parking equipment carriers. In the utility model, a laser distance measuring instrument being connected with a computer is arranged on a carrier; a parking device is provided with a laser emission plate. When laser emitted by the laser distance measuring instrument is irradiated on a reflecting plate and is reflected to the laser distance measuring instrument again, the laser distance measuring instrument causes data to be introduced to a processor of the computer, and the laser distance measuring instrument can accurately judge the current location of the carrier, judge requested position according to vehicle access commands, compute direction, speed and decelerating fixed point position of motion, send commands to a drive system and cause the carrier to smoothly reach any parking position.

Description

Mechanical parking equipment carrier laser ranging locating device

This practical a kind of laser ranging locating device, i.e. mechanical parking equipment carrier laser ranging locating device of relating to.

The carrier that uses in the mechanical parking equipment of the prior art, three kinds of the main utilization of range finding and location alignment sensor range finding location, scrambler range finding location and limit switch range finding location.Use alignment sensor to find range and locate, cost height, installation complexity, debugging are frequently, the cycle is long, system failure rate is high and be not suitable for large-scale parking apparatus; Use scrambler range finding location mainly can cause range error because of reasons such as wheel slips; Use limit switch range finding location degree poor, equipment failure is many.

The utility model is at existing problems, and its purpose is to provide a kind of and uses the laser ranging position location by computer control and the high mechanical parking equipment carrier of distance accuracy.

The utility model is to be installed on carrier (2) one sides by the laser range finder that will connect computing machine (1) level, and many water chestnuts laser-bounce plate (3) is installed at the opposite side of parking apparatus, laser range finder can move horizontally with carrier, when laser range finder (1) sends laser, be mapped on the reflecting plate (3), reflected back laser range finder (1) again, laser range finder imports data into the processor (4) of PLC computing machine (5).The PLC system is by calling the distance value of filtrator, can judge this carrier retaining front position accurately, and according to the instruction of access car, judge the position that requires arrival, thereby the direction of motion of calculating, speed, deceleration fixed position, send instructions to drive system, make carrier can arrive any one parking stall stably.Its measurement range is at 100-150000MM.

Fig. 1 is one-piece construction figure of the present utility model.

Fig. 2 is the utility model and computing machine johning knot composition.

Below in conjunction with accompanying drawing the utility model is described in detail.

Embodiment: adopt CP340 Laser Measuring instrument, and its level is loaded on mechanical parking equipment carrier one side, at the opposite side of parking apparatus the plate of diamond pattern laser-bounce more than one is installed, its face is 0.01-1 square metre.On the PLC computer system, set up a DME-2000 type serial communication module, and transmit the data cable line and laser range finder links by one, thereby the processor that can import the distance and the position data of institute's measuring car into the PLC system, its measurement range can be at 100-150000MM, thereby can accurately judge the current location of carrier, and can be according to the instruction of picking up the car, judge the position that requires arrival, thereby the direction of motion of calculating, speed, deceleration point position, send instruction and give drive system, make carrier can arrive any one parking stall stably.After using this equipment, a large amount of hardware devices are reduced, failure rate reduces greatly, and its debugging is more convenient, but and shock resistance, dustproof, waterproof, under the situation of shake and vibrations, also can be accurately stable measure range deviation, the full-automation of realization parking apparatus.

The utlity model has range accuracy height, good stability, anti-interference ability is strong, volume is little, do not have Accumulate poor, debug easily characteristics, it is used on the large-scale parking apparatus, can reduce a large amount of hardware Equipment, fault rate reduces greatly, is a kind of product that is suitable for.
